MBR partitions use a single byte to represent the type, and we don't
have any corresponding uuid type for that, so this wouldn't work.
Adding a UUID type for MBR should be the way forward.

The GPT partition side seems good to me, but it would be nice if the
description in the manual included the expected formats of the UUIDs,
depending on the partition table type.  Examples would be welcome there
as well.

Best,
